The root as a sink for chloride under chloride-salinity

In pot experiments carried out in 2005 and 2006, tolerance to sodium chloride salinity of 4 cultivars of perennial ryegrass (Lolium perenne) ('Nira', 'Stadion', 'Ronija', 'Darius') was studied. Three concentrations of NaCl in medium (earth + sand): 0.0 mM (control); 50 mM; 100 mM, were used in the investigations. In three successive crops of grass, fresh weight yield of leaves, stomatal conductance, photosynthesis intensity, content of chlorophyll and PS II maximum quantum yield (Fv/Fm) were determined. The obtained results showed that perennial ryegrass is a species tolerant to NaCl salinity. Among the studied cultivars, cv. 'Ronija' showed the highest tolerance, whereas cv. 'Nira' showed the lowest. The growth of perennial ryegrass plants under salinity conditions was limited by low stomatal conductance of leaves and photosynthesis, but not by the photosynthetic activity of chlorophyll and its contents.

Chloride Salinity

Greenhouse and field studies were conducted to assess the salinity tolerance of Siberian larch (Larix siberica L.) under conditions found on the Canadian prairies. In greenhouse studies top and root growth of Siberian larch seedlings began to decline under sulphate salinity between 2.0 and 5.3 mmhos/cm (electrical conductivity of saturation paste extract) indicating that Siberian larch is moderately salt-tolerant. The addition of chloride caused an initial top growth decrease, chlorosis, and reduction in survival between 1.4 and 3.6 mmhos/cm; the latter salinity level being associated with 20 meq/L of Cl and 1.5% Cl in the saturation paste extract and needles, respectively. Field studies conducted under naturally occurring sulphate salinity indicated that height of 10-yr-old Siberian larch began to decline between 3.5 and 4.0 mmhos/cm. Changes in needle mineral composition were related to the ratio or increase of ions in the soil solution, and the physiological effect of the sulphate and chloride anion. In general, presence of chloride salinity caused a greater increase to occur in the cation content of the needles than sulphate salinity. Accumulation of organic anions in the needles was also related to cation concentration and needle chlorosis.

Intercellular Co2

To elucidate the comparative effect of chloride and sulfate salinities on photosynthesis and yield components in rice, plants of Oryza sativa (cv. I Kong Pao (salt-sensitive)) were exposed in nutrient solutions to 20 mM Na2SO4 or 40 mM NaCl (electrical conductivity of c.a. 4.30 dS m−1 for both solutions) from seedlings to maturity stage. Both types of salt induced a strong decrease in net photosynthesis (AN) at the seedling and tillering stages, while the intercellular CO2 concentrations (Ci) remained unaffected. Instantaneous transpiration (E) and stomatal conductance (gs) decreased at the tillering and seedling stages, respectively, only in plants exposed to NaCl. Chloride salinity also strongly decreased photosynthetic pigments, while no impact was detected in response to Na2SO4. All yield-related parameters were affected by salinities, but NaCl was significantly more deleterious than Na2SO4 for the mean number of tillers produced per plant, spikelets sterility and non-viable pollen percentage. In contrast, both types of salinity similarly impacted the percentage of fertile tillers and 1000-grain weight. At the grain level, more than 90% of toxic ions (Na+, excess of Cl− and S6+) accumulated in the hulls, thus preserving the internal part of the caryopses from toxic ion injuries.
